2、對(duì)蝦(Penaeusmonodon)生長(zhǎng)及水質(zhì)的影響。D1、D5和D6的對(duì)蝦增重率和特定生長(zhǎng)率顯著高于D2和D4(P<0.05);D5和D6的飼料系數(shù)顯著低于D2和D4(P<0.05)。D4和D5的蛋白質(zhì)消化率顯著高于D1~D3各飼料(P<0.05)。第20天水體化學(xué)需氧量(COD)D1最低,顯著低于D5和D6(P<0.05)。第40天時(shí)D5和D6的COD顯著低于D1一D4各飼料(P<0.05),D2的氨氮(NH4+一N)最低,顯著低于D4~D6各飼料,總氮(TN)、總磷(TP)分別在D4、D6最低。第60天時(shí)D1和D2的NH4一N顯著低于其他
3、各飼料(P<0.05),D5和D6的TN顯著低于D1一D4各飼料(P<0.05),而TP在D2最低,顯著低于D1和D4(P<0.05)。氮(N)排放率在D1和D6顯著低于其余4種飼料(P<0.05),磷(P)排放率則D1最低。投喂D1、D5和D6能夠使對(duì)蝦獲得較優(yōu)生長(zhǎng)性能,且對(duì)水體污染最小。關(guān)鍵詞:商品飼料;斑節(jié)對(duì)蝦;生長(zhǎng)性能;水質(zhì)中圖分類號(hào):S816.32文獻(xiàn)標(biāo)志碼:A文章編號(hào):2095—0780一(2013)06—0020—07Efectsofdiferentbrandsoffeedsongrowthofblacktigershrimp(P
